TOUCH SCREEN
[attachment=44390]
Definetion
A touch screen is a computer display screen that is sensitive to human touch, allowing a user to interact with the computer by touching pictures or words on the screen.
Touch sensitive surface
The touch sensitive is an extremely durable and flexible glass or polymer touch responsive surface, and this panel is placed over the viewable area of the screen. In most sensors, there is an electric current or signal going across the screen, and a touch on the surface causes a change in the signal depending on the touch sensor technology used. This change allows the controller to identify the location of the touch.
Controller
The controller is an electronic device that acts as the intermediary between the screen & the computer. It interprets the electrical signals of the touch event to digital signals that a computer can understand. The controller can be integrated with the screen or housed externally.
Capacitive touchscreen
It is consist of glass panel with a coat of charge-storing material on its surface. when the panel is touched, a small amount of charge is drawn at the point of the contact. Circuits located at each concern of the screen measure the difference in change & send the information to the controller for the calculating position of touch.
